2. The background: BPS solutions

• BPS conditions and vanishing energy

• Solutions and Killing spinors

  • with fixed scalars and 8 Killing spinors
  • with 1/2 susy (4 Killing spinors)

• Examples

  • fixed scalars: double extreme STU wall. One brane can be pushed to ?
  • Calabi - Yau wall: restricted distance between branes
